Title: Frequency synthesizer
Inventor: NAGAYA TETSUO
IPC: H03L7/18
Filed: 1996-02-23
Abstract: PROBLEM TO BE SOLVED: To suppress spurious radiation without causing deterioration such as a phase lag and phase noise by increasing a comparison frequency for a phase comparator so as to separate a loop band width from the phase comparison frequency. SOLUTION: A comparison frequency is given to a multiplier 4, in which the frequency is multiplied and the multiplied frequency is given to a BPF 5 to make the band width narrow and the resulting frequency is given to a phase comparator 6, where the comparison frequency is compared with a reference frequency. Thus, the loop band width is made apart from the phase comparison frequency. Then a phase difference signal outputted from the phase comparator 6 is given to a loop filter 7, from which a DC voltage is outputted to a spurious radiation suppression LPF 8. Its output is given to a VCO 1 to control an oscillated frequency of the VCO 1.

Title: Heat exchanging device
Inventor: UEMATSU KENGO
IPC: F28D15/02
Filed: 1979-05-18
Abstract: PURPOSE:To make heat exchanging device durable longer by selecting each heat pipe for material, fin pitch and fin height according to properties of a working gas in a separate type heat exchanger. CONSTITUTION:A heat exchanging panel 2 is formed by selecting a large fin pitch, a low fin height and, where necessary, a heat resisting material for a heat pipe in a high-temperature gas duct. Where the heat pipe has a large fin pitch and a low fin height, dusts in a high-temperaure gas are hard to accumulate on the pipe and easy to remove at the same time. Then, where the gas in a low-temperature gas duct 3 has a corrosive component, that of corrosion resistance will be selected for the heat pipe. For the high-temperature gas containing much dust, a pipe 6G with a large fin pitch p will be positioned. In addition to efficient heat exchange, a heat exchanging device can now be made durable longer thereby.

Abstract: PURPOSE:To judge the adequacy of a signal level in real time by providing a means for comparing, evaluating, and judging a semiconductor device external signal level and an internal signal and an external reporting means at an input, an output, and an input/output terminal. CONSTITUTION:A semiconductor LSI 1 is connected to a host system 2 which controls the part which is higher in order than the LSI 1 and an external bus 3. The LSI 1 consists of an internal bus 5 which receives an input from the bus 3, passes the signal to the inside of the LSI 1, and sends and receives signals in the LSI 1 to and from an input interface part 4, a control part 6 which controls the LSI 1, an arithmetic part 7, and an output interface 8 which outputs the arithmetic result. When the adequacy of the output terminal of the LSI 1 is evaluated, the host system 2 sends a command to the LSI 1 through the external bus 3. The LSI 1 receives the command by the control part 6 through the interface part 4 and internal bus 5. The control part 6 interprets the command to wait for a chance for evaluation, and switches the signal level 11 when the chance comes to perform sampling, thereby sending the sampled data to a decision part 14.
